[quote name='ArecxP']Does anyone know if I can return 1 game and exchange it for another of the same price? Or will I have to bring all 3 games that I bought?[/QUOTE]
YMMV, but my local store has let me do straight across exchanges on even the 'Free' game in the past. What I usually end up doing with these sales is finding only 2 games I really want, and 1 more 'filler' game that I'm on the fence about.
Last time I did this was I think with:

Darksiders & LittleBigPlanet Goty, with

Halo ODST. I ended up returning ODST a few days later for Gears of War 2. Come to think of it...I think the clerk even just credited my account for the cost of ODST, and I ended walking out of there with 2 other games inc. GoW2....hmmm, been a while since I thought about this lol.
[quote name='strait edge follower']Wow that is a great haul with great variety as well. Oh and do not I repeat DO NOT return the world ends with you as its one of the best and most unique rpgs I've ever played ![/QUOTE]
I'll give it another solid go while I still have a week to think about it, I'm just getting tired of the endless extended tutorial hehe. I just finished "Day 2", and theres just so much talking talking talking talking introduce-minor-gameplay-function talking talking talking talking repeat. I'm really digging the music/art aesthetic tho. It reminds me a lot of Jet Set Radio, which is why I picked up the game in the first place.
